Final answer:
The simile in the passage is "each as round as a ball," comparing the shape of the eggs to a ball's roundness using the word 'as'.
Step-by-step explanation:
The simile in the quoted passage from Hatchet is not explicitly stated, but we can identify a simile in the descriptive fragment: "each as round as a ball." This comparison, using the word 'as', directly compares the roundness of the eggs to the roundness of a ball, which is characteristic of a simile. A simile is a figure of speech that compares two different things using the word 'like' or 'as' to create a vivid image or to make a descriptive point more clear.
Here the eggs itself is a oval structure organisms and the eggs are compared here with the roundness of the ball, though we know the eggs are not exactly round, but in figurative way it is compared with the ball.
